Kubb is a modular code-generation framework that turns OpenAPI descriptions into type-safe TypeScript code, Zod schemas, and TanStack Query integrations. It is used by TypeScript developers to generate client code and related interfaces from API specifications. The catalogue contains extensions such as skills, commands, hooks, agents, and a plugin that support Kubb workflows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00035 | $0.00553 |
| Opus 5 | $0.00017 | $0.00277 |
| Sonnet 5 | $0.00007 | $0.00111 |
| Haiku 4.5 | $0.00003 | $0.00055 |
Grade A, and why
output scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Output Skill
This skill instructs agents on importing and using the code Kubb generates from an OpenAPI/Swagger spec.
When to Use
- Writing application code that calls the generated client or hooks
- Writing tests that use the generated mocks or schemas
- Wiring generated files into an app
What It Does
- Explains where generated code lands
- Shows how to discover the real exports and a plugin's options
- Lists the rules for keeping generated code in sync
Where output lands
Kubb writes generated code under the output.path from kubb.config.ts (for example ./src/gen),
organized into the folders each plugin sets through its own output.path (for example models,
clients, hooks). Generated files carry a Do not edit manually banner and are rewritten on
every kubb generate, so change them by editing the spec or config and regenerating.
Export names derive from the spec's operationId and schema names. Casing and grouping are
configurable, so read the generated files for the exact names and signatures rather than assuming
them.
Find what was generated
Inspect the real output instead of guessing:
- Read
kubb.config.tsfor the top-leveloutput.pathand each plugin'soutput.path. - List the output directory for the actual file and export names.
- Read an installed plugin's
Optionstype (node_modules/@kubb/plugin-<name>/src/types.tsor the published type declarations) for its options and defaults, and the plugin's docs page (https://kubb.dev/plugins/plugin-<name>) for dependencies. Use those as the source of truth rather than assuming an option name.
Import from a folder's index.ts when output.barrel is set, otherwise import the file directly.
Rules
- Never edit files under
output.path. Edit the spec or config and rerunkubb generate. - Import generated code instead of copying it, so a regenerate keeps callers in sync.
- Configure the runtime client once. The client functions and framework hooks share it.
- Typecheck after regenerating so a spec change that broke a call site shows up.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

output is a skill published in the GitHub repository kubb-labs/kubb (1,791 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 553 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
